static InputReader.desc_output_to_input(outfile, infile, objective='force', optimizer='lsq-exact', header=None, ftol=0.01, xtol=1e-06, gtol=1e-06, maxiter=100, threshold=1e-10)Source

Generate a DESC input file from a DESC output file.

DESC will automatically choose continuation parameters

Parameters:

  • outfile (str or path-like) – name of the DESC input file to create

  • infile (str or path-like) – path of the DESC output equilibrium file

  • objective (str) – objective type used in the input file

  • optimizer (str) – type of optimizer

  • header (str) – text to print at the top of the file

  • ftol (float) – relative tolerance of the objective function f

  • xtol (float) – relative tolerance of the state vector x

  • gtol (float) – absolute tolerance of the projected gradient g

  • maxiter (int) – maximum number of optimizer iterations per continuation step

  • threshold (float) – Fourier coefficients below this value will be set to 0.
